 * The plugin produces a lot of warnings, over 100 in the last few days, with PHP
   8.2.28.
 * It’s always these two:
 * PHP Warning: Undefined array key “action” in /nas/content/live/PRIVATE/wp-content/
   plugins/nelio-ab-testing/public/helpers/class-nelio-ab-testing-runtime.php on
   line 233
 * PHP Warning: Undefined array key “ga4ClientId” in /nas/content/live/PRIVATE/wp-
   content/plugins/nelio-ab-testing/includes/hooks/woocommerce/compat/session.php
   on line 80
 * Can you all fix this?
 * ChatGPT has some suggestions:

 * Thanks!

 * Thanks for the heads up, Dustin. The next release will fix both issues.
